On the occassion of the centennial of Graham's solitary appearance for the Giants during an uneven win in Brooklyn, Kinsella told The Associated Press that he was drawn to the ballplayer while examining a baseball encyclopedia that he had received as a gift.

"I found this entry for Moonlight Graham. How could anyone come up with that nickname? He played one game but did not get to bat," Kinsella recalled to The AP in 2005. "I was intrigued, and I made a note that I intended to write something about him."

“My job was to get on base,” Greenberg recalled. “I certainly was successful in doing that."

While Greenberg never did reach first base he did secure a baserunner for the Cubs after being hit by the first pitch that he saw in the majors. The 92-mph fastball zipped out of the left hand of Florida Marlins relief pitcher Valerio de los Santos, rising and drifting away from the target set up by catcher Paul Lo Duca. Greenberg turned away but the ball hit him solidly in the back of his head. The pitched projectile struck him behind his right ear with his helmet absorbing only some of the force from the fastball, as recounted by The New York Times. The thundercrack of the impact sent Greenberg down and brought Lo Duca up. The backstop waved for help from the dugout as Greenberg cradled his head, lying on his back.

The mild concussion suffered when he was hit by the pitch eventually gave way to positional vertigo, according to ESPN and The New York Times. As he struggled to return to the big leagues, Greenberg spent the 2006 season bouncing around the minors in the Cubs' and Dodgers' farm systems. He landed a spot in spring training with the Kansas City Royals ahead of the 2007 campaign, when "OTL" documented his comeback attempt.

Not for lack of effort on his part, Greenberg has yet to make it back to the plate in major league uniform. Per MLB rules, a plate appearance that ends in a hit-by-pitch does not count as an official at-bat. His supporters want him to get his "one at-bat."

Graham never got the chance that Greenberg did to face a big league pitcher. Who is the luckier player? In "Field Of Dreams," the fictionalized Graham's one wish is to get the chance that Greenberg got in 2005.

"I never got to bat in the major leagues. I would have liked to have had that chance. Just once. To stare down a big league pitcher. To stare him down, and just as he goes into his windup, wink. Make him think you know something he doesn't. That's what I wish for. Chance to squint at a sky so blue that it hurts your eyes just to look at it. To feel the tingling in your arm as you connect with the ball. To run the bases - stretch a double into a triple, and flop face-first into third, wrap your arms around the bag. That's my wish, Ray Kinsella. That's my wish?"

Is this truly how Graham felt? Kinsella didn't know. Phil Alden Robison, who wrote the screenplay, didn't know. Neither did Burt Lancaster, who portrayed Graham in the film. Who could have known if the lack of a turn at-bat nagged Graham throughout his life?

Perhaps Adam Greenberg. Of course, Greenberg's turn at the dish came and went in less time than Graham may have needed to wink at his opponent.

"You can make any comparison you want," Greenberg responded to Bob Holzman of ESPN in 2007 when asked about the comparisons to Graham. "I know in my heart that.. I mean.. I'm.. that's not going to be it. I'm not going to be a 15-minute-of-fame.. you know.. one pitch guy in the major leagues."

As his story again garnered attention late in the 2012 MLB season, Greenberg's Twitter profile described him first as "Professional Baseball Player" and secondly as an "Entrepreneur." The name and website of a dietary supplement was then listed.

According to the SABR Baseball Biography Project, the Evening World wrote in 1905, “Dr. Archie Graham, who is to join the Giants as soon as he completes his examinations at the Baltimore Medical College, is known as ‘Moonlight’ because he is supposed to be as fast as a flash.”

Veda Ponikvar, one of the many in Chisholm, Minn. who was cared for by Dr. Graham after his stint with the Giants, recalled two other possible explanations for the famous nickname.

Unlike Graham, who stuck with his medical studies even as a roster spot with the Giants waited for him, Greenberg seems to have maintained a laser focus throughout his professional career, telling Barry Bearak of The New York Times that “Failure is not an option” in 2007.

With the dogged determination of man who refused to even consider other career paths, Greenberg kept chasing his big league dream, preferring to think it had been deferred by that errant pitch rather than denied. An athletic outfielder who brought speed to the basepaths, Greenberg had never been a particularly strong hitter before getting beaned. In the season following the incident, his batting average dropped to a paltry .206. With his age advancing and his offensive production declining, Greenberg found himself playing for the unaffiliated Bridgeport Bluefish in 2008.

“In his first movement as a hitter to get ready to hit, sometimes it messes up his swing,” Bluefish manager Willie Upshaw told The Shoreline Times in 2011, describing what he perceived as the lingering effects of the HBP. “His first movement is a little bit passive, not going toward the hitting zone.”

When the independent Bluefish began play in the Atlantic League in 2012, Greenberg was no longer with the club. At age 31, the door would seem to have finally closed on Greenberg.

Liston posted a petition at Change.org and created a promotional video in hopes of convincing Cubs owner Tom Ricketts to provide an at-bat to Greenberg in the team's final homestand of the season. With the Houston Astros visiting Wrigley Field from Oct. 1-3, there would be no playoff implication to the games. To Liston and the more than 14,000 who added their names to the petition, this would be the ideal chance to make Greenberg's dream come true. That the move could come at the expense of another aspiring big leaguer clinging to his own roster spot was a price Greenberg's supporters seemed willing to pay.

"Adam made the big leagues based on merit in 2005," Hoyer told the Chicago Tribune in an email. "While it is unfortunate he got hit in his first at-bat, he is in the Baseball Encyclopedia as a major leaguer and he should be incredibly proud of that. We wish him the best, but there are no plans to add him to the roster now or in the future."

With his career with the Cubs seemingly fixed in his past, Greenberg was tweeting about his future on Tuesday. The Connecticut native is competing for a spot on Team Israel for the 2013 World Baseball Classic.
